37743: Difficulty in sighting the moon in industrialized areas

In my area it is belive that one can not see the first moon due to the fact that there are many industry .what do you say to this. and what is the size of the first moon.

Praise be to Allaah.

It is not difficult to sight the new moon when it appears. Although it may be
difficult to sight it in some places because there is too much smoke, it will not be difficult to sight it in other areas where the sky is
clearer.

No matter how high smoke and buildings may be, they can never cover the moon like
the clouds. The Prophet (peace and blessings of Allaah be upon him) has told us that if it is cloudy and we cannot see the new moon, then we
must complete the month of Sha’baan and regard it as having thirty days.

So either the new moon can be seen through the smoke and buildings, in which case
we should fast when it is seen;

Or it can be seen in another place where the sky is clearer, so we should fast
when it is seen;

Or it is too cloudy and we cannot see it, so we should regard Sha’baan as having
thirty days.

With regard to the size of the new moon when it appears, it is very small and
cannot be seen except by one who has good eyesight.
